The cannabis market in France lacks reference tools in French: most of the calculators available are in English, with no sources quoted, and ignore the french legal framework. Newsweed has built these tools to fill this gap, with a transparent methodology based on published scientific literature.
Each tool cites its sources directly on the tool page. The formulas used are documented and reproducible. Legal thresholds are those in force in France at the time of the last update.
